abstract = {Bone is a complicated heterogeneous, viscoelastic, anisotropic material. Its properties
depend on the nature of mechanical forces in addition to the location as well as the age, sex and race
of the subject. Human humerus bones retrieved from cadavers were selected and separated in to
cortical and cancellous parts. They were heat treated at different temperatures 400°C, 600°C and
800°C respectively to study the crystalline nature and composition of cortical and cancellous region
of the humerus bone separately. Hydroxyapatite (HAP) was present as the major phase in the bone
powders at 600 and 800°C with well resolved peaks along with other mineral phases of calcium
phosphate. No amorphous phases were present indicating that the crystal structure of calcium
phosphate compounds is present in crystalline form. FTIR studies further confirm the presence of
phosphate vibrational modes of the entire bone mineral along with the presence of carbonates and
hydroxyl groups.}
